How did you install the font? I tend to recommend TUG TL to my users as it adds everything and it just works. Lots of people seem to have problems with either MikTeX or the Ubuntu version of TL.

@daleif I will now try to reinstall it with the built-in package manager, because it's possible that it was an on-the-fly install during compilation which MiKTeX automatically does, although the installation procedure should be the same.

Might be an idea. You could test to see if it finds some of the font files, e.g. kpsewhich TeXGyrePagellaX-Regular.pfb

I uninstalled the newpx package, ran a full update of MiKTeX, and reinstalled the package. Then the compilation failed with an etex.sty not found error. I had to install the package miktex-etex-base-2.9 from the package manager because the earlier miktex-etex-base has been removed as obsolete during the update. After that everything worked again.
